Seasonal Hooking Mortality of Flathead Catfish and Blue Catfish

This study was conducted to estimate the summer and winter hooking mortality of flathead catfish (pylodictis olivaris) caught on trotlines in the Colorado River and Kerrville Reservoir, Texas, and blue catfish (Ictalurus furcatus) caught on trotlines in Livingston Reservoir, Texas. Water temperatures averaged 12.2 and 13.3 C, respectively, during February and March flathead catfish winter experiments, and 27 C during summer experiments. Water temperatures averaged 12.5 and 24 C, respectively, during winter and summer blue catfish experiments. Flathead catfish (range = 352-675 mm total...
